universal type product tio2 pigment titanium dioxide paints r996 factory

The raw material used in this method is FeSO4. In order to maintain the Fe3 + concentration in the reaction medium in a specific range, reducing agent iron sheet is added in the reaction process. Iron yellow crystal seed was added and air was introduced to synthesize iron yellow under certain pH conditions. The method mainly includes two steps: (1) firstly, FeSO4 · 7H2O is used as raw material, NaOH or NH3 · H2O is used as precipitant or pH regulator, and air is used as oxidant to prepare crystal seed; (2) Iron yellow is produced by two-step oxidation with crystal seed, FeSO4, iron sheet and air.

  • Titanium Dioxide (TiO2), a naturally occurring oxide of titanium, exists in two primary crystalline forms - Anatase and Rutile. Among these, Rutile TiO2, with its superior whiteness and high refractive index, has garnered significant attention in the coating sector. Its exceptional good whiteness imparts a brilliant, clean appearance to coatings, making it an indispensable ingredient in various applications such as architectural coatings, plastics, paper, and even food.
  • TiO2 is also used in the production of plastics, where it serves as a whitening agent and UV stabilizer. By incorporating TiO2 into plastic products, manufacturers can enhance their appearance, increase their lifespan, and improve their resistance to sunlight and weathering. Additionally, TiO2 helps prevent the degradation of plastic materials, ensuring that they retain their properties and performance over time.
